If none of them show up, you'll probably need to check the mail server's logs to see what happened to them.

The mailinator.com address is a handy public access email address. Mail with any username @ mailinator.com and goto the site and enter the username you used to view all of it's recent mail.

Your code worked fine when I copied it to my server and changed $recipient to the address of my own gmail account.

I've just tried sending a message to your Yahoo account. If it doesn't come through it may be because the e-mail is being blocked by Yahoo for some reason. If so try sending a message to a different (non-Yahoo) account and see if that works.

Do you even have a hosting account here? I see that you only have 1 post and 5 points. You can't send e-mails from here, or run any kind of scripts for that matter without an active account.
